>Virtual memory is built into many operating systems.
	Since they each need it only when they are running, i.e., never at
	the same time, the swap spaces of all but the currently running
	one are being wasted.  It would be more efficient for them to
	share a single swap space.  This is possible, but can require a
	bit of hacking.  The Tips-HOWTO contains some advice on how to
	implement this.  </P
